Python 中的 fixture 和 fixtures

class MyTestCase(unittest.TestCase):

    def my_fixture_setup(self):
        pass

    def setUp(self):
        super(MyTestCase, self).setUp()
        self.my_fixture_setup()

class MyTestCase(unittest.TestCase):

    def my_fixture_cleanup(self):
        print("++++ my_cleanup")
           
    def setUp(self):
        super(MyTestCase, self).setUp()
        self.addCleanup(self.my_fixture_cleanup)

from __future__ import print_function

        self.frobnozzle = 42
        print("++++ MyFixture.setup()")
        
    def cleanUp(self):
